CVE-2026-18749
CriticalCVSS 9.8Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
The type=track branch authorizes only on _is_my_case(t_attach.case) and never checks VinceTrackAttachment.shared. A coordinator-uploaded case artefact that has NOT been marked shared is still retrievable by any case member who has (or is sent) its uuid — leaking not-yet-released coordinator material to vendors on the case.
Risk Assessment
Unintended disclosure of confidential coordinator materials before official release, potentially compromising the coordination process.
Recommendation
Add a check for the shared flag before allowing access to case artefacts.
